Seeking while playing Widevine/AVC can cause a stall #719
Description
Version
ExoPlayer 2.19.1
More version details
While playing back Widevine protected AVC content, I notice the player can get stuck in a state after seeking where it is in a buffering / not loading state. I can see plenty of errors / warnings coming from the device CCodecX classes, but Exoplayer itself never recovers, and appears to load indefinitely.
When performing another seek to a different timestamp (even by just 1ms) playback recovers.
This seems to occur on our Widevine/AVC content as well as the one available inside the ExoPlayer demo app.
Our app is currently using ExoPlayer 2.18.1 - I've reproduced it in the ExoPlayer demo app for 2.18.1 and 2.19.1.
Devices that reproduce the issue
Pixel 5, Android 14
Devices that do not reproduce the issue
Pixel 7 Pro, Android 13
Reproducible in the demo app?
Yes
Reproduction steps
- From the exoplayer demo app, select Widevine DASH(MP4, H264) -> HD (cenc)
- Seek somewhere on the seek bar
- If the seek was successful, retry step 2.
- Observe that seeking occasionally indefinitely hangs, and leaves the device in a buffering but not loading state
- Seek again to regain playback
Expected result
Seeking does not incur indefinite buffering states.
Actual result
Seeking hangs indefinitely, and the user must seek again to regain playback.
Media
I can provide Widevine/AVC protected content via the attached email if needed, but I have reproduced it via the sample content in the Exoplayer app.
